LAMP-EXTINGUISHER.

Specification of Letters Patent.

Patented Sept. 20, 1910.

To all whom it may concern:

Be it known that we, (1) ISADOR GREEN- WALD, (2) JosnPH BLAUSTEIN, and(3) MORRIS Z. Wnrss, (1) subject of the King of Hungary, 2) and (3)citizens of the United States of America, residing at (1) and (2)Pittsburg, and (3) McKeesport, in

the county of Allegheny and State of Pennsylvania, have invented certainnew and useful Improvements in Lamp-Extinguishers, of which thefollowing is a specification, reference being had therein to theaccompanyin drawing.

This invention relates to lamp extinguishers, and the primary object ofour invention is to provide a lamp burner with simple and effectivemeans for snufling or extinguishing the flame of the wick when the lampis accidentally tilted or upset.

A further object of our invention is to furnish'an oil lamp burner withspring held shutters adapted to be automatically released to extinguishthe flame of a lamp, thereby preventing explosions, fires and thedestruction of property and lives.

These and such other objects as may hereinafter appear are attained by amechanical construction that is simple, applicable to various types ofoil lamp burners, and highly efficient as a safety device for lamps.

The invention will be hereinafter specifically described and thenclaimed, and reference will now be had to the drawings forming a part ofthis specification, wherein there is illustrated a preferred embodimentof the invention, but it is to be understood that the structuralelements thereof can be varied or changed as to the size, shape andmanner of assemblage without departing from the scope of the invention.

Reference will 'now be had to the drawings wherein Figure 1 is a sideelevation of a portion of a lamp provided with the extinguisher,

Fig. 2 is a similar view partly broken away and partly 1n verticalsection, Flg. 3 1s a perspective view of the lamp burner partly brokenaway and partly in section, Fig. 4 is a front elevation of a portion ofthe extinguisher, showing the same in an open position, and Fig. 5 is asimilar view showing a portion of the extinguisher in a closed position.

In the accompanying drawings the reference numeral 1 denotes the body orreceptacle portion of a lamp, said body being sup ported upon a suitablepedestal or base 2 and adapted to contain an illuminating oil, askerosene. The top of the body 1 is provided with a neck 3 and screwed orotherwise mounted in the neck 3 is the lower reduced threaded end 4 of acylindrical burner casing 5, said casing having the upper end thereofprovided with a cap 6.

7 denotes a vertical wick guide carried by the cap 6 and the reduced end4 of the casing '5, and in this guide is adjustably mounted in the usualmanner a wick 8.

9 denotes posts carried by the cap. 6 and connected to said posts is astepped annular chimney support 10 having a plurality of horizontalannular platforms 11, 12 13 and 14. The platform 11 has diametricallyopposed inner-edges thereof connected by a spider 15 through whichextends the wick guide 7, and upon this spider adjacent to the roundedsides of'the guide 7 are mounted bearings 16 and 17,. livotallyconnected to said hearing by pins 18 are the arms 19 of shutters 20,these shutters when closed extending over the upper edge of the wickguide whereby the flame of the wick will be snuffed or extinguished.

21 denotes small gear wheels or racks mounted upon the lower ends of thearms 19 at one side of the extinguisher, these small gear wheels orracks meshing with each other, whereby the shutters can be moved inunison. Mounted upon the spider 15 is a compression spring 22 adapted tobear against one of the shutters and close both of said shutters whenreleased.

denotes a bearing carried by the spider 15 and pivotally connected tosaid hearing, as at 2 1 is an arm 25 having the upper end thereof benttoward the wick guide 7 and provided with a tooth 26 adapted to engagethe inner edge of one of the shutter arms 19 and hold said shutters inan open position. The lower end of the arm 25 extends below the spider15 and is provided with a curved right angular extension 27 having areduced end 28. The lower end of the arm is connected by a coiled spring29 to one of the arms of the s ider 15, said coiled spring normallyholding the tooth 26 in engagement with the arm 19 of the shutter.

30 denotes a pin adapted to engage the reduced end 28 of the extension27,'said pin being carried by the upper end 31 of a bracket 32, theupper end of said bracket being loosely mounted in the reduced end 4 ofthe casing 5 and in the cap 6 carried by said casing, The bracket 32 isprovided with an opening having a weighted rod 33 suspended from thereduced end 4 of the burner casing 5, said rod having the upper endthereof provided with a head 34 held by the reduced end 4 of the burnercasing 5, while the lower end thereof is provided with a weight 35. Therod 33 directly above the bracket 32 and adjacent to the head 34 isprovided with a conical shaped head 36 adapted to normally engage thebracket 32.

37 denotes a lever pivotally mounted, as at 38 upon the horizontalplatform 12 of the support 10, said lever having the upper end thereofprovided with a tooth 39 ada t ed to extend into an opening 40proviolied therefor in the arm 19 of the shutter 20, which opposes theshutter under the action of the spring 22. The lower end of the lever 37is curved to extend through an opening 41 in the platform 13., saidlever extending downwardly under the platform 14 and upwardly to providea handle 42.

A lamp. extinguisher constructed in accordance with our inventionoperates in the following manner :-When'the lamp is accidentally tiltedor upset, the weight 35 causes the rod 33 to swing by gravity, and asthe head 36 of said rod engages the bracket 32, said head will belowered and the pin 30 thereof will lower the reduced end 38 of theextension 27 swing the upper end of the arm 25 to the right whereby itwill release one of the. shutters 20, and the spring 22 engaging theshutter will immediately close said shutters. The rod 33, weight 35 andhead 36 constitute gravity actuating means for moving the arm 25, and torestore the shutters to their normal position after the lamp has beenplaced in an upright position, the lever 37 is moved to swing the.

shutters open whereby the spring pressed arm 25 can again engage one ofthe arms of the shutters. The lever 37 constitutes means in conjunctionwith the gear wheels: 21 for restoring the. shutters to: their normalposi tion.

The lamp extinguisher in its entirety is made. of light and durablemetal similar to ordinary lamp burners and can be used in connectionwith any type of burner having a fiat wick.

Having now described our invention what we claim as new, is

1. A lamp extinguisher comprising the combination with a burner casing,a chimney support carried thereby, and a wick guide extending throughsaid casing, of a pair of pivoted shutters adapted to be closed over theend of said Wick guide, gear c0nnections between said shutters forsimultaneously opening and closing them when one of the shutters isshifted, means 'connected to one of said Shutters for shifting itwhereby both of the shutters will be actuated, a pivoted lock armadapted to normally engage one of said shutters and maintain theshutters in open position, a vertically movable member engaging saidlock arm and adapted when shifted in one direction to move the lock armclear of the shutter whereby the shutters can be simultaneouslyactuated, and a gravity movable element extending through said memberand provided with means for shifting the member when said element ismoved.
